Hamburger

What is it?

One thin beef patty sits on a plain bun with pickle slices, diced onions, ketchup, and mustard. Cooked from frozen on a flat-top grill, the patty gets a light sear on both sides, then gets tucked into soft bread without cheese or sesame seeds. Compared with the Quarter Pounder and Big Mac buns in McDonald's lineup, this one stays simpler and smaller. It's also one of the chain's most basic beef sandwiches, often sold as a value item and used in Happy Meals, which keeps the ingredient list short and the format familiar.
